For example, when n = 1 we have: s = a(r1 −1) r −1 = a Then r can take any value apart from 1. Also, note that if a = 0 then s = 0 and again r can take any value apart from 1.

WebWhen you multiply ar^ (n-1) and -r together the first thing you can do is distribute the negative sign, which gives you -ar^ (n-1) * r. The variable r can also be expressed as r^1. So you get -ar^ (n-1) * r^1. Next you can pull out the -a which gives you (-a) (r^ (n-1)) * r^1. Then you can simplify and get (-a) (r^ (n-1+1)).
